Product Introduction of FEP Dispersion Coating DS603A/B

FEP DS603A/B is an off-white aqueous FEP dispersion stabilized with a non-ionic surfactant.It is a general-purpose dispersion that can be used to impart some the unique properties of FEP to end products that would be difficult to make using traditional melt extrusion processes.It can be used to coat or impregnate porous structure,or to make thin films.It can be coated and melt bonded to PTFE resin or used as a hot melt adhesive.

1:Effect of vacuum on FEP Dispersion coating compactness

The rotating speed of the extruder is 12r/, the wire enters the extruder at room temperature (15 ℃), the processing temperature is 370, the wire is naturally cooled by air at room temperature, the wire diameter is 0.6 mm, and the diameter of the wire after coating on FEP is 1.2 mm.

2: Effect of preheating temperature on FEP Dispersion coating tightness

With the increase of preheating temperature, the adhesion force decreases. When the wire is preheated, the contaminants on the surface of the wire and the moisture in the air can be degraded when the wire is preheated at high temperature. The volatile gas increases the gap between the coating layer and the metal wire and reduces the friction between them. So as to reduce the adhesion, that is, the degree of compactness decreases with the increase of the preheating temperature of the conductor.
